TELEPHONE.

SPECIFICATION forming part of Letters Patent No. 549,304, dated November 5, 1895.

Application filed September 24, 1895. Serial No. 563,467. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL ALEXANDER, a citizen of the United States of America, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Telephones,of which the following is a description, reference being had to the accompanying drawings, wherein Figure 1 is an elevation, mainly sectional, of a device and apparatus embodying said improvement. Fig. 2 is a similar View, so far as it goes, of a modification.

The object an d purpose of the improvement is the production of an improved and simplified apparatus for transmitting to a central station the sound produced by a falling coin at a pay-station.

In the accompanying drawings, the letter a denotes what I call a sounder-case, it being a box for the reception of coins as they are deposited at pay'stations preparatory to a paid use of a telephone-line. The letter Z) denotes the slot or mortise through which the coin is dropped, and as it drops it strikes the bell or sounder c, and it is the sound thus produced that it is desired to transmit to the pay-station, signifying thatthe person at the transmitter has paid his fee and is entitled to be served.

' The letter (1 denotes a hollow sound-con-' ducting post attached on the top of the sounding-box and with its lower open end contiguous to the sounder, that it may readily take and transmit the sound there produced.

The letter 2 denotes a transmitter-case containing within it the ordinary transmittingdiaphragm with suitable telephonic wire connection s. This transmitter-case is pivotally attached to the post (Z by the pivot f, to the end that the transmitter-tube, into which the operator speaks and which forms practically a part of the transmitter-case, may be raised or lowered at the outer end to accommodate persons of different statures.

The letter g denotes a tube formed, so far as it goes, like a circle whose axis is the pivot f. It is rigidly attached to the transmittercase and also telescopically attached to the hollow post (I. This curved tube 9 may take hold of the transmitter-case in front of the transmitter-diaphragm, as shown in Fig. 1, or behind it, as shown in Fig. 2.

I claim as my improvement In combination, the sounding-case a, the sounder c, the hollow sound conducting post (I, the transmitter-case e pivotally attached to the post, and the curved tube 9 rigidly attached to the transmitter-case and telescopically attached to the post, all substantially as described and for the purposes set forth.

SAMUEL ALEXANDER.
